Everything is in the title, here some things that I tried :
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[self setWantsFullScreenLayout:YES];
[[self view] setNeedsLayout];
CGRect frame = self.view.frame;
frame.size.height += 20.0;
[[self view] setFrame:frame];
Could you tell me what to do? I thing it might be something else in the code, since with a simple clear project, it's working.
